The resistance readings indicate the transformers are probably good, and the caps have been replaced.

Do you have access to another monitor, or some CCFLs. At this point the best way to troubleshoot would be to substitute known good CCFLs. You don't have to pull them out of the panel, simply arrange the two panels close enough that you can hook the CCFLs in the 'test' monitor to the inverter in your monitor.

The other choice is to disassemble the LCD panel in your monitor and check the CCFLs and wiring for problems.
